IMPROVEMENT IN CAKE-STIRRERS.

Specification forming part of Letters Patent N o. 121,336, datedNovember 28, 1871.

To all whom it may concern:

Be it known that I, SARAH M. CLARK, of Beaver Dam, in the county ofDodge and State of Wisconsin, have invented a certain Improved Oake-Stirrer 5 and I do hereby declare that the follow-' ing is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawing forming part of this specification.

This invention relates to improvements in the construction ofcake-stirrers 5 and consists in the construction and the arrangementhereinafter described. Y

Figure 1 is a side view of my improved cakestirrer, partly in sectionand partly in elevation; and Fig. 2 is a top view, also partly insection.

Similar letters of reference indicate corresponding parts.

A is a sheet-metal vessel or cup for holding the dough and other mattersto be compounded. It may be of any si'ze or form, and is provided withthe metal brackets or ears B B for attachment by screws C to a plate orbar, D, extending over the top, and having at one end the clamping-plateE and screw F for attachment to the edge of a table, shelf, or othersuitable support. The barD is slotted at the end, as shown at J, so thaton loosening the clamping-screw thereat the latter may be drawn outofthe slot-also out of the slot in the ear-and thus save the timerequired to detach it by screwing. It also leaves the bar D free to bemoved in such manner as to disconnect it from ear B by drawing the screwout of a slot in the end of it. This arrangement admits of attaching anddetaching the vessel readily. Gr is a vertical bar, so attached to thetop of bar D and arranged that it will afford a bearing in thehorizontal part at the top for the top of the stirrer-shaft H, the lowerend of which rests in the step I, in the center of the bottom of thevessel A. The said upright bary G also furnishes a support for thedriving-wheel K, which is mounted on the stud L projecting from the sideof said upright. M is a pinion mounted on the top of shaft H and gearingwith the driving-wheel K, which has a handle or hand-crank for turning,to give motion to the said stirrershaft, on which, within the vessel A,are arranged the concavo-convex arms N, on the outer ends of which aremounted the vertical blades or plates O, also shaped in concavo-convexform. Both the arms and the plates have the large holes P through them,as shown, through which and the spaces between the arms and plates thesubstance to be stirred or beaten is caused to pass as the said arms andplates are rapidly rotated against it, thereby beating, mixing, andpreparing it as is required. The arms of the stirrers may be put on theshaft in sections, so that they may be removed for using more or less asmay be required for different substances or quantities. The stirrers maybe turned in either direction, as may be required by the nature orcondition of the substance under treatment. I may arrange the wheel M atthe lower side of the wheel K.

4 Having thus described my invention, I claim as new and desire tosecure by Letters Patent- 1. The vessel A, brackets B, screws C, bars DG E, set-screw F, gear-wheels K M, shaft H, arms N, and vertical platesO, all combined and arranged substantially as specified.

2. The bar D, having the slot J, in combination with the ears B B', alsohaving slots to facilitate the attaching and detaching of the vessel,substantially as specified.

SARAH M. CLARK.
